Good Friends' Stable's Private Zone, who closed last season with his third grade I stakes win in New York, is scheduled to make his 6-year-old debut Saturday, March 7, in the $300,000 Gulfstream Park Handicap (gr. II).

Fort Larned, a three-time grade I winner, including the 2012 Breeders' Cup Classic, was represented by his first foal Jan. 26. Fort Larned will stand in 2015 at Adena Springs South near Williston, Fla.

Now in its eighth year, the Breeders' Cup Challenge provides automatic bids to horses that win top stakes in the U.S. and throughout the world that correspond with one of the 13 Breeders' Cup World Championships races.

While preparing 2013 Preakness (gr. I) runner-up Itsmyluckyday for a start in the $75,000 Best of the Rest Stakes to be run April 26 at Gulfstream, trainer Eddie Plesa Jr. revisited last year's Triple Crown experience.

Dogwood Stable's Palace Malice, on the shelf since an even sixth-place finish in the 2013 Breeders' Cup Classic (gr. I), showed no signs of rust with a gritty victory in the $250,000 Gulfstream Park Handicap (gr. II) March 8.

Palace Malice and Itsmyluckyday were among the best of the 3-year-old crop in 2013. On March 8, the two return for the first time in 2014 as part of an eight-horse field set to go in the $250,000 Gulfstream Park Handicap.

Multiple grade I winner Jackson Bend heads a field of 11 as part of a one-two punch for trainer Stanley Gold in the $100,000 Gulfstream Park Sprint (gr. III); Gold also has 2013 winner Fort Loudon in the Feb. 8 race.

Ribo Bobo, who has won six of seven since he was claimed, and the solid mare My Pal Chrisy top the fields for the Florida Sunshine Millions Sprint and Florida Sunshine Millions Filly & Mare Sprint Jan. 18 at Gulfstream.
